Satou Ichirou used to be a "Dream Soldier" in middle school: a delusional youth who believes that they are like the protagonists in fantasy anime and light novels. Once he enters high school, however, he throws all of that away in hopes of being a normal high school student.

But when he forgets his textbook at school one day and sneaks into the school that night to get it, he runs into a mysterious girl dressed in blue robes who claims that she is a magician.
